The controversial prosecutor whose mom is TV’s Judge Judy is reportedly under investigation in a forgery case.

Adam Levy, the Putnam County district attorney, is being probed for his role in the prosecution of a county sheriff candidate who allegedly submitted phony signatures on his nomination petitions.

The state Attorney General’s Office believes Levy’s office ignored a complaint that a rival candidate did the same thing, according to The Journal News.

“There are strong inclinations that there may have been things done improperly,” state investigator Paul Schneeloch told the paper.

Levy, the son of TV’s “Judge Judy” Sheindlin, was already being probed in an unrelated case for allegedly leaking grand jury information in a child-rape prosecution that involved his former live-in personal trainer, Alex Hossu, an illegal immigrant from Romania. Levy is also accused of helping to finance the defense case and offering legal advice.

Hossu was busted earlier this year for allegedly choking and raping a 13-year-old girl.

Authorities said the attacks took place in 2010, when the victim was 13, and came to light when the girl, now 15, told a school counselor.

Levy has a daughter who is also 15. Authorities said she is not the victim.
